I would not recommend Plumbing Force because my (Aug 2020) experience was they that failed to correctly assess the plumbing faults associated with a non functioning Saniplus toilet, recommended an expensive (and unnecessary) solution, and did not respond in a constructive way to my subsequent complaint to them. 1. I contacted Plumbing Force because i had a saniplus that did not work and I thought it needed replacing. 2. Plumbing Force said they needed to visit to make an assessment of the problem - cost £25 3. The Plumbing Force plumber visited and suggested that he might be able to fix the Saniplus if it was obstructed but the charge would be at an hourly rate - cost £118.80 4. The Plumbing Force plumber did not detect the bit of plastic in the U bend of the toilet bowl, or the bit of plastic in waste pipe of the saniplus pump but did say the saniplus needed replacing 5. Plumbing Force provided an estimate for replacement of the Saniplus (£780 incl VAT plus labour at hourly rate £118.80) which I thought was inflated 6. I bought and fitted a Saniplus (which were available for £500 incl VAT online),- but there was still a problem 7. I contacted an accredited saniplus plumber who found the problem ( a piece of plastic in the U bend of the toilet bowl), and fixed the old saniplus with a new diaphragm/membrane -total cost £140 The end result was that I paid Plumbing Forces £118.80, but took their advice to get a new Saniplus £496.90 (though ignored their estimate of £898.80 to replace the saniplus). The net result was that I paid about £750 to fix a problem that should have cost £140. If I had taken up the Plumbing Force estimate it would have cost over £1000 to fix the problem.
